Reports from across the Iranian capital said despite the several-day-long ploy and intensive media provocations by the West, the Opposition call for riots and unrests in Tehran failed to attract supporters and calm and everyday life prevailed in the Iranian capital as usual.

An Opposition conglomerate comprising antirevolutionary elements from the terrorist Mojahedin-e Khalq Organization (MKO) to monarchist groups and affiliates of the defeated presidential candidates in the June 2009 elections, Mehdi Karroubi and Mir-Hossein Mousavi, had issued an open call for their supporters to stage protests and riots in the Iranian capital on Sunday, but official and unofficial reports said calm remained undisturbed and intact in the city.

Earlier reports had warned that a number of MKO members have infiltrated the country to start illegal gatherings specially in Tehran to set the stage for opening fire on the public and eventually bring the country into chaos.

Also, a senior Iranian legislator had warned this morning that MKO members and hirelings have hatched a plot to start unrests in Tehran this afternoon in a bid to open fire on the civilians to make the police and security forces reciprocate their gunfire.

MP Seyed Mohammad Javad Abtehi told FNA that the MKO members planned to kill the people who gather in streets to put the blame on the Iranian security forces in order to create a rift between the nation and government.

In relevant development, Iran's Deputy Police Chief Ahmad Reza Radan told FNA this afternoon that Tehran's police squads had arrested a terrorist who was carrying explosive materials and intended to explode a bomb in the Iranian capital today.

"This person intended to use the explosive material for sabotage and terror operation," Radan added.

In scattered small riots in western Tehran on Monday afternoon, several MKO teams opened fire at the public and police troops, killing one university student on the scene and wounding 9 more. One of those wounded in the incident also died later at the hospital.

Tehran's police tried to disperse the rioters, but did not reciprocate the gunfire. Police officials announced on Tuesday that most of those wounded in the incident were security and police troops.

According to police officials, the seditionists had hatched a plot to get the police and security forces involved in armed clashes to allege that they had been treated violently, but they failed to do so.

Eye-witnesses and FNA dispatches from the Monday unrests said that the seditionists, whose number remained lower than 200 altogether, were forced to flee the scene after thousands of people overwhelmed the streets in support of the government.

Later, tens of thousands of people along with a number of parliament members staged a sit-in at a central square in Tehran Tuesday night, demanding the government to take strict action against the seditionists and their leaders.

Sources close to the MKO later revealed that the terrorist organization had played a key role in the Monday unrests in the Iranian capital.

The Habilian Association, an Iran-based human rights group formed by the family members of the Iranian victims of terrorism, quoted reliable sources as saying that MKO's surrogate ringleader Maryam Rajavi had dispatched several operational teams to Tehran and had been in constant contact with the team members until the end of unrests.

"Mayam Rajavi was in direct contact with the operational units dispatched to Tehran and ordered them to spray live fire on the public who had risen to stand against the few seditionists," Habilian said.

"In this terrorist operation which took place in Tehran's Qasroddasht neighborhood on Monday February 14, the Basiji student, Saneh Zhaleh, was martyred and four others were severely wounded," it added.

"A student activist in France disclosed that over 350 members of the MKO had been sent from several European and Asian countries to Tehran and other major Iranian cities, based on plan drawn by the main ringleader of the MKO, Massoud Rajavi," the Habilian website said.

The website said the MKO teams intended to start riots, set fire on garbage cans, destroy public amenities and private properties and shoot and kill the large number of the self-driven people who had come to defend the Islamic Republic and the government against the seditionists in a bid to provoke the police and security forces into reciprocating the gunfire to create a pool of blood in the capital and to escalate the unrests.

But after police refrained from armed clashes with the seditionists and the public pushed the seditionists back, the MKO plot ended in failure, the website added.
